FENCE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 335,399, dated February 2, 1886,

Application tiled October 24, 1885. Serial No. 180,818. (No model.)

T0 LZZ whom it may concern:

Beit known that I, JOHN B. Trucs, a citizen of the United States, and a resident of Dayton, in the county ot' Montgomery and State of Ohio, have invented certain new and useful Improvements in Fenee-ltlaking Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective View of my improved fence-wire twister. Fig. 2 is a longi` tudinal sectional view ot' the same. Fig. 3 is a cross-section on linexx. Fig. 4 is a similar section on line 1/ y, and Fig. 5 is a rea-r View of the device.

Similar letters of reference indicate corresponding parts in all the ligures.

My invention has relation to that class of machines for making picket and wire fences, in which strands of wire are twisted around the pickets by means ofrevolving twisters,through which the wire strands pass; and it contemplates certain improvements in the construction of the revolving twisters, which will be hereinafter more fully described, which will admit of the picket being dropped between the bifurcated arms of the twister, and by means of which the tension upon the strands of wire may readily be regulated at will.

As an illustration of that class of machines to which my present improvement is applicable, I would, forthe sake of convenience, refer to the machine for manufacturing picketfences, for which Letters Patent of the United States, No. 316,84),were granted to me on the 28th day of April, 1885; but I desire it to be understood that this invention is equally applicable to other machines of the same class, which are operated upon substantially the same principle.

By reference to the accompanying drawings it will be seen that myimproved twisterA consists of a tube,B,having a suitable gear-wheel or sprocket-wheel, C, secured upon it, by means of which the twisters are revolved in the usual manner, and having a cap, D, at its rear end, Which cap increases in width toward its closed end, which is formed with two diametricallyopposite diverging and iiaring perforations, E E, while the forward end of the tube is provided with a bit'urcated head, F, having perfou rations G G at the inner ends of the twisterarms H H, and having grooves I in the outer sides ofthe said arms, forming continuations ot' the perfor-ations at their inner ends. The middle portion of the head F is ofa greater diameter than at either end, and the bottom of' each groove forms two inclined planes with an angle at their intersection, so that the wires in passing from the holes G to the outer ends of the arms pass over this angle, which helps to regulate the tension. The holes G are made diverging, and have a rounded head, L, between them, so that the wires can be more easily passed through them from the rear. The inner sides of the parallel twister-arms are rounded, as shown at J, and the inner end ot' the slot formed between the arms is also rounded, as shown at K, so that all the surfaces of the slot formed between the twisterarms are rounded. By means of this construction the pickets can be placed in position between the arms, even if the machine is rotated a trifle too much or too little after twisting the wires around the last picket. The cap upon the rear end of the twister-tube is screwed upon the said end, so that it may be adjusted with its perforations in any desired relative position to the apertures in the sides of the head and to the grooves in the arms, and by having the pcrforations in the cap diverging vthe wires are held farther apart, and consequently they are not so liable to become fouled by reason of being alternately twisted in op` posite directions, and by making the hole flaring kinks and splices in the wires pass into and through them more readily and without the danger of catching and breaking.

In using this device the Wires are drawn in pairs from a suitably-arranged spool to the twistcrs, after these have been adjusted to their desired positions and relative distances, and each strand ofa pair of Wires is drawn through one of the perforations in the cap ot' the twister, whereupon each strand is carried out through its respective aperture in the head, placed in its groove in the twister-arm, and at last secured to the post in the usual IOC manner. By turning the cap the relative made by the twisters.

It will readily be seen that this twister may be used with other machines besides with the machine hereinbefore'referred to, the twister being capable of being applied to any machine having the wire strands passing in pairs through revolving twisters, and it will also be seenthat the twisters may be revolved by other means than by sprocket-wheels and chains, as described in said patent, and that the cap may be used with a twister having tubular instead of grooved arms, all these applications of elements of my invention being practicable without departing from the spirit of my invention.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesy l.. A twister-head fora machine for making wire and picket felices, consisting of atube having a twister having oppositely-situated apertures upon one end and an adjustable cap upon the other, said cap having two oppositely-situated diverging apertures, and means for rotating said head, substantially as and for the purpose set forth.

2. A twister-head for a machine for making wire and picket fences, consisting of a tube having a twister having oppositely-situated apertures upon one end and an adj ustable cap upon the other, said cap having two oppositely-situated arin g diverging apertures, and means for rotating said head, substantially Vas and for the purpose set forth.

3. A twister-head for a machine for making wire and picketfences, consisting of a tube having a twister secured thereto, said twister being of alarger diameter at its middle portion,

and having two diverging apertures at its rear part, and a rounded head between said apertures, and means for rotating said head, substautially as and for the purpose set forth.y

4. A twister-head for a machine for making wire and picket fences, consisting of a tube having a twister secured thereto, said twister having. apertures G, communicating with the tube, being of a larger diameter at its middle portion, and having its front part bifurcated,

forming arms, the outer sides of which are v grooved and the inner sides rounded, and means for rotating said head, substantially as and for the purpose set forth.

5. A twister-head for a machine for making wire and picket fences,consisting ofatube having atwister secured thereto,said twister being ofalarger diameter at its middle portion than at either end, and having diverging aperturesat its rear end, and being bifurcated at its front end, forming arms,the outer sides of which arms are grooved, the bottoms of said grooves being two inclined planes forming an angle at their intersection, and means for rotating saidhead, substantially as and for the purpose set In testimony that I claim the foregoingas my own I have hereunto atliXed my signature in presence of two witnesses.
